While corn is generally more sensitive to yield loss from weeds, soybeans are more sensitive to Canada fleabane. In field trials, Peter Sikkema found the average yield loss in soybean to be 61 per cent versus 52 per cent in corn.

The Canada fleabane problem

At current corn and soybean prices, the value of control is at an all-time high

Reading Time: 4 minutes If you think you’ve heard the same message about glyphosate-resistant Canada fleabane more than once, you’re probably right. But that doesn’t mean you should pay less attention, especially since it’s particularly important if you’re growing corn. The problem of resistant biotypes isn’t getting much better, says Peter Sikkema, weed scientist with University of Guelph’s Ridgetown […] Read more

Finding new uses for corn and its byproducts is one way to encourage continued production of corn (and soybeans).

Are corn and soybeans on the wane?

Could other crops erode their dominance in Eastern Canada, and if so, which ones?

Reading Time: 5 minutes In the next 10 to 30 years, could corn and soybeans became lesser crops in Ontario and Eastern Canada? What would that look like and how might that unfold?  Before you say, “It’ll never happen,” think back to 1992 and changes such as transgenics, GPS and precision ag technologies and production capabilities that have virtually […] Read more


Mike Cornelissen has been has upgraded his equipment three times as manufacturers have rolled out new designs.

Strip till catching on 

Residue management and improved soil health are among the benefits

Reading Time: 4 minutes In theory, strip till should boost yields, especially in corn, where the practice is most usually used. Clearing residue from a seed zone and berming the soil so it warms faster in preparation for spring planting sounds like an obvious benefit. More equipment manufacturers have adapted systems to enable “multitasking” such as combining strip till […] Read more

The RNAi trait in SmartStax Pro prevents the production of a specific protein in CRW, without which it can’t survive.

A new trait for corn rootworm

The RNAi trait will launch in Canada in 2023 and complement current Bt Cry protein traits

Reading Time: 5 minutes Late in 2019, agronomists in mid-western Ontario urged producers to opt out of growing continuous corn or corn on corn in an effort to break the cycle of resistance that had developed within corn rootworm. The issue had arisen because of resistance to three of four Bt Cry proteins, reducing the effective modes of action […] Read more

#CropPatrol: Corn seen to be very sensitive to weed interference

Reading Time: 2 minutes Ontario farmers grow most of the corn produced in Canada, with 2.2 million acres produced in 2020, a value of more than $2 billion. However, the crop is sensitive to early weed interference. The Weed Science Society of America (WSSA) reported an average corn yield loss of 50 per cent if weeds are left uncontrolled. […] Read more

South Africa looking at another large corn crop in 2022-23

Reading Time: < 1 minute MarketsFarm — South Africa is reported to be well on its way to producing another 15 million-plus-tonne corn crop in 2022-23, according to the U.S. Department of Agriculture (USDA) attaché in Pretoria. However, it will be far less than the USDA’s current estimate of 17.3 million tonnes. Nevertheless, if the attaché’s forecast were to hold, […] Read more
